Julianus Pomerius was a Christian priest in fifth century Gaul. He wrote five treatises, only one of which, "De Vita Contemplativa", survives. He was renowned in rhetoric and grammar and was friends with Ennodius and Ruricius. He appears to have fled from Mauritania, North Africa to Gaul to escape the Vandals, towards the end of the century. He became an abbot and a teacher of rhetoric at Arles, where he was known for the teacher of Caesarius, a great conservator of Augustine of Hippo's teachings. It is known that their titles probably emphasized the ascetic ideal.
